Remote power, air conditioning & refrigeration from common solar-heated
bath-water collectors!


Powered by thermal sources from Solar, Geothermal,  Co-generation, &   Biomass



"By eliminating the primary impediment of the low-temperature Rankine cycle, Matteran Energy changes solar thermal power into an extremely cost-effective prospect."



An independent thermodynamic analysis by SATOP (NASA's Space and Technology Outreach Program) concludes that, in addition to much lower temperature abilities, the theoretical efficiencies are 15% improved over comparable Rankine cycles heated to 150ºF (65ºC).

A series of successful prototypes have culminated in a residential-scaled power unit recently proven effective at refrigeration and air conditioning.

The Sterling Cycle was invented in 1995 by Jeff Sterling of Miami, Fl. It should not be confused with the unrelated S t i r l i n g  engine invented in 1816.

Low grade solar heat
(think "sun-drenched garden hose") will air condition & power your home!!

When Jeff Sterling envisions “solar thermal power”, he pictures the mild warmth in a sun-drenched garden hose fueling his new residential-scale power plant. Why? Because no matter how you look at it, the least expensive form of solar energy is collected as mildly warmed water.

And because Sterling’s power process produces more electricity from mildly warmed water than was previously imagined possible, his idea of an economical solar thermal power plant is in stark contrast to those incredibly hot and expensive mirrored solar farms so often touted by the media.

Sterling’s power plant produces economical electricity from mildly warmed water. The beauty is that there are no dangerous pressures or temperatures. It’s like a steam engine running at the temperature of a cup of hot chocolate.

According to the IEA, 1.3 billion people have no access to electricity, much less the “luxury” of refrigeration. Yet, everybody has access to the mild warmth that fuels Sterling’s power cycle.

Developers of other solar thermal power plants keep moving in the direction of progressively higher temperatures and larger mirrored solar fields. But Sterling’s power plant remains economical while operating on a residential scale fueled by low-cost solar collectors.

“Our development company, Matteran Energy, has progressed the extra step to produce economical electricity, refrigeration and air conditioning from solar heated bath water."

“This past September, we proved our process on a useful scale. We ran our 1/3rd-ton air conditioner down to 25º Fahrenheit. We're making ice and air conditioning from warm water! What could be more simple, or less expensive?” Developers at Matteran Energy are preparing Sterling’s residential-scaled prototype for a public demonstration of its capabilities.

In addition to the sun, Sterling envisions his power plants fueled by other readily available low-temperature renewable sources of energy. “We’ve identified a wide-spectrum of global demand, ranging from the co-generation of electricity fueled by the waste-heat of a skyscraper’s air conditioner, down to something as ‘green’ as powering a mountain cabin’s electrical appliances fueled by the heat rising up its wood-burning chimney.”
